Context

“Such like concealment is what is meant by an ambush which may be lawfully employed in a just war. Nor can these ambushes be properly called deceptions, nor are they contrary to justice or to a well-ordered will. For a man would have an inordinate will if he were unwilling that others should hide anything from him. This suffices for the Replies to the Objections. _______________________ FOURTH ARTICLE [II-II, Q. 40, Art. 4] Whether It Is Lawful to Fight on Holy Days? Objection 1: It would seem unlawful to fight on holy days.” source
